Description

一种定位方法及相关装置
本申请要求于2022年10月31日提交中国国家知识产权局、申请号为202211366276.2、申请名称为“一种定位方法及相关装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及定位技术领域，尤其涉及一种定位方法及相关装置。
背景技术
在以智能手机为代表的电子设备中，基于位置的服务(location based service，LBS)已成为电子设备上一项必不可少的基础服务。
目前，用户对室内定位的需求日益迫切。例如，车库找车、隧道定位，等等。特别是对于大型的商场、机场和火车站等地方的车库面积大、车位多、路线复杂，使得用户通过室内定位在车库找车的需求更加强烈。由于在室内时，电子设备上的全球卫星导航卫星系统(global nagvigation satellite system，GNSS)模块通常接收不到卫星信号，无法通过卫星信号进行定位。因此，需要借助电子设备上的惯性测量单元(inertial measurement unit，IMU)等硬件以及导航模块等软件模块实现室内定位。这就需要用户在进入室内时主动开启电子设备上的导航应用，在开启导航应用后，导航应用会启动电子设备的导航模块和IMU等硬件，持续发起连续定位。
但是，当用户忘了提前打开电子设备上的导航应用时，电子设备无法获取到室内中用户的位置。
发明内容
本申请提供了一种定位方法及相关装置，实现了电子设备可以在识别到将要进入到室内区域的地理围栏时，自动开启导航定位，以获取电子设备进入到室内区域内的实时位置。
第一方面，本申请提供了一种定位方法，应用于电子设备，该电子设备包括惯性测量单元IMU、全球导航卫星系统GNSS模块，该IMU用于检测该电子设备的IMU数据，该GNSS模块用于在开启时获取GNSS数据；该方法包括：该GNSS模块处于关闭状态；当该电子设备检测到该电子设备处于车载状态且该电子设备进入到车库的地理围栏时，该电子设备开启该GNSS模块，并通过GNSS模块获取该GNSS数据；该电子设备基于该GNSS数据和该IMU数据确定该电子设备的实时位置；当该电子设备检测到车辆停车时，该电子设备将基于该GNSS数据和该IMU数据确定出的第一位置，确定为停车位置；该电子设备显示该停车位置。
通过本申请提供的一种定位方法，在电子设备上的GNSS模块没有被开启的情况下，若电子设备检测到进入指定室内区域的地理围栏且电子设备处于车载状态后，电子设备可以启动GNSS模块，通过GNSS模块获取到的GNSS数据以及IMU数据，发起持续导航定位，当电子设备检测到停车时，获取到停车位置。这样，即使用户在未提前开启电子设备上的GNSS模块时，电子设备也可以在进入到室内区域后持续获取到用户的实时位置，例如，停车位置。
在一种可能的实现方式中，该电子设备检测到该电子设备处于车载状态，具体包括：若该电子设备检测到该IMU数据满足第一预设条件，该电子设备确定该电子设备的处于车载状态。
其中，该第一预设条件包括该电子设备的移动速度在第一预设速度与第二预设速度之间和/或该电子设备的移动加速度大于预设加速度，其中，该第一预设速度小于该第二预设速度。
这样，由于一般情况下，电子设备上的IMU长期处于开启状态，因此，电子设备可以通过IMU测量的IMU数据，确定电子设备是否处于车载状态，充分利用了IMU。
在一种可能的实现方式中，该电子设备检测到该电子设备处于车载状态，具体包括：若该电子设备检测到与该车辆之间建立了蓝牙连接，该电子设备确定该电子设备处于车载状态。
这样，电子设备可以准确识别电子设备处于车载状态。

其中，该第二预设条件包括该电子设备的移动速度为0。
这样，由于一般情况下，电子设备上的IMU长期处于开启状态，因此，电子设备可以通过IMU测量的IMU数据，确定车辆是否处于停车，充分利用了IMU。

这样，由于地理围栏数据比较多，因此，可以对地理围栏数据进行分区域存储。电子设备可以先从地理围栏数据库中检测电子设备所处的目标活动区域对应的一个或多个地理围栏数据，再检测电子设备是否进入车库的地理围栏，可以节省数据的运算量，也减少了运算器件中数据的存储量。
在一种可能的实现方式中，该电子设备基于该GNSS数据和该IMU数据，确定出该电子设备的实时位置，具体包括：当该电子设备在第一时刻通过该GNSS模块获取到该GNSS数据时，该电子设备基于该GNSS数据，解算出该电子设备在第一时刻的位置；当该电子设备在第二时刻未通过该GNSS模块获取到该GNSS数据时，该电子设备基于该IMU数据，确定该电子设备在该第一时刻到该第二时刻之间的位移信息；该电子设备基于该电子设备在该第一时刻的位置和该第一时刻到该第二时刻之间的位移信息，确定出该电子设备在该第二时刻的位置。
这样，可以在车库等室内区域，GNSS信号比较弱，无法获取到GNSS数据时，也可以持续获取到电子设备在室内区域的实时位置，获取到停车位置。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
下面介绍本申请实施例中提供的在车库中找车的实现方式。
由于用户对室内定位的需求日益迫切，例如，车库找车、隧道定位，等等。特别是对于大型的商场、机场和火车站等地方的车库面积大、车位多、路线复杂，使得用户通过室内定位在车库找车的需求更加强烈。
方式1：为了实现车库找车，可以在车库部署专用的停车检测设备或器件(例如，摄像头、感应器，等等)。该停车检测设备或器件可以检测车库中车辆的停车位置并将车辆的停车位置发送给与该停车检测设备配套的应用程序。用户就可以在该应用程序上查看该车辆的停车位置。但是，通过这种方式实现车库的找车，需要在车库部署相关的硬件设备或器件，还需要用户在手机等电子设备上下载相应的应用程序，导致部署成本和维护成本较高，难以大规模推广。
方式2：手机等导航设备可以通过IMU传感器、GNSS模块和摄像头等等，进行自主导航定位，获得车库停车位置。但是，这种方式需要用户在进入车库前手动打开导航应用，通过导航应用启动导航定位模块进行导航定位，当手机等导航设备进入车库后，由于GNSS模块通常接收不到卫星信号，无法通过卫星信号进行定位，因此，可以通过IMU传感器和/或摄像头等器件完成航位推算，实现定位。如果用户没有提前通过导航应用启动导航定位模块，用户在停车时手机等导航设备通常无法获得停车位置。如果导航定位模块一直开启，手机等导航设备的功耗大。
因此，本申请实施例中提供了一种定位方法，可以实现给多个室内区域(例如，车库、隧道、山洞，等等)配置地理围栏。在电子设备上的导航定位模块没有被开启的情况下，若电子设备检测到进入指定室内区域的地理围栏且电子设备处于车载状态后，电子设备可以启动导航定位模块，发起持续定位，当电子设备检测到停车时，获取到停车位置。其中，导航定位模块包括GNSS定位模块和车载航位推算(vehicle dead reckoning，VDR)定位模块/航位推算(dead reckoning，DR)定位模块。这样，电子设备可以在识别到将要进入到室内区域时，自动开启导航定位模块，以获取电子设备进入到室内区域内的实时位置。
在本申请实施例中，室内区域不限于车库、隧道、山洞，等等类型的区域，还可以有其他类型的室内区域。为了叙述方便，本申请实施例中以室内区域为车库进行示例性说明。

下面介绍本申请实施例中提供的一种定位方法。
图8示例性的示出了本申请实施例中提供的一种定位方法的流程示意图。
如图8所示，该方法可以包括如下步骤：

S802、电子设备100通过IMU传感器获取IMU数据。
其中，IMU传感器可以包括陀螺仪和加速度计。IMU数据可以包括陀螺仪数据和/或加速度数据。
S803、电子设备100基于IMU数据确定电子设备100的活动识别(AR)状态。
其中，活动识别(AR)状态可以包括车载状态、骑行状态、步行状态、静止状态，等等。
在一种示例中，电子设备100可以从IMU数据中确定出电子设备100的移动速度和移动加速度。当移动速度和/或移动加速度满足第一预设条件时，电子设备100可以确定电子设备100处于车载状态。其中，第一预设条件包括电子设备100的移动速度在第一预设速度与第二预设速度之间和/或电子设备的移动加速度大于预设加速度，其中，第一预设速度小于所述第二预设速度。例如，当电子设备100的移动速度大于40公里每小时(km/h)且小于180km/h时，电子设备100可以确定电子设备100的AR状态为车载状态。又例如，当电子设备100的移动加速度大于0.2g时，其中，g为标准重力加速度，g＝9.8m/s2。又例如，当电子设备100的移动速度大于40km/h且小于180km/h，且电子设备100的移动加速度大于0.2g时，电子设备100可以确定电子设备100的AR状态为车载状态，等等。上述示例仅仅用于解释本申请，具体实现中，还可以基于IMU数据通过其他条件判断出电子设备100的AR状态，在此不作限定。
在一些示例中，当电子设备100确定出蓝牙模块已经与车辆建立了蓝牙连接时，电子设备100可以确定电子设备100的AR状态为车载状态。其中，电子设备100与其他设备建立蓝牙连接时，可以获取到其他设备的设备类型，因此，当电子设备100车辆建立蓝牙连接时，电子设备100可以获取到车辆的设备类型为车类型。当电子设备100确定出电子设备100与车辆之间蓝牙连接断开时，电子设备100可以确定车辆处于停车状态。
在一些示例中，电子设备100可以与车辆建立蓝牙连接，当车辆启动时，车辆可以通过蓝牙连接向电子设备100发送车辆状态信息1，该状态信息1用于指示车辆已启动。当车辆停车熄火时，车辆可以通过蓝牙连接向电子设备100发送车辆状态信息2，该车辆状态信息2用于指示车辆已停车。当电子设备100接收到车辆状态信息1时，电子设备100可以确定电子设备100处于车载状态。当电子设备100接收到车辆状态信息2时，电子设备100可以确定车辆处于停车状态。
S804、电子设备100获取电子设备100当前所在的第一活动区域。
方式1：电子设备100可以通过蜂窝模块获取到电子设备100当前所处的蜂窝小区，并基于电子设备100所处的蜂窝小区从多个热点活动区域中确定出电子设备100所处的第一活动区域。其中，蜂窝小区信息与热点活动区域存在对应关系，例如，一个蜂窝小区可以对应一个热点活动区域，又例如，多个蜂窝小区可以对应一个热点活动区域。
方式2：电子设备100可以通过Wi-Fi模块获取到Wi-Fi数据，其中，Wi-Fi数据可以包括发送Wi-Fi信号的Wi-Fi接入点的MAC地址、IP地址、Wi-Fi信号强度，等等。由于Wi-Fi接入点的位置一般是固定的，一些Wi-Fi接入点的MAC地址和/或IP地址以及这些Wi-Fi接入点的位置可以存储在互联网的服务器中。当电子设备100获取到Wi-Fi信号的MAC地址和/或IP地址后，电子设备100可以通过Wi-Fi接入点的MAC地址和/或IP地址，从服务器上查询该Wi-Fi接入点的位置区域，并将该Wi-Fi接入点的位置区域确定为电子设备100当前所在的第一活动区域。
方式3：电子设备100可以通过GNSS模块获取到GNSS位置和观测量信息。其中，该GNSS位置的定位精度较差(例如定位范围大于10m)，无法用于电子设备100的导航定位。电子设备100获取到GNSS位置后，可以基于该GNSS位置，从多个热点区域中确定出电子设备100所处的第一活动区域。
方式4：电子设备100还可以接收用户预先输入的位置信息，电子设备100可以基于用户预先输入的位置信息，从多个热点活动区域中确定出电子设备100所处的第一活动区域。
本申请实施例中，不限于通过上述几种方式确定电子设备100所在的第一活动区域，还可以通过其他方式确定出电子设备100的第一活动区域，在此不作限定。
S805、电子设备100基于用户当前所在的第一活动区域从地理围栏数据库中确定出第一活动区域内一 个或多个地理围栏的地理围栏数据。
其中，地理围栏数据库中可以包括有多个热点活动区域内的地理围栏数据。该地理围栏数据库保存在电子设备100本地，也可以保存在云服务器上。
S806、电子设备100判断是否电子设备100的AR状态为车载状态且电子设备100进入到第一活动区域内车库的地理围栏。
其中，电子设备100可以基于电子设备100检测到的蜂窝小区信息和/或Wi-Fi数据和/或GNSS位置，以及第一活动区域内一个或多个地理围栏的地理围栏数据，判断电子设备100是否进入到第一活动区域内车库的地理围栏。其中，地理围栏数据中可以包括有蜂窝小区信息、Wi-Fi指纹库数据、GNSS位置等信息。其中，该蜂窝小区信息可以包括该地理围栏所在位置的蜂窝小区。Wi-Fi指纹库数据包括该地理围栏所在位置检测到的Wi-Fi信号的标识信息和信号强度信息。
当电子设备100检测到的蜂窝小区信息与第一车库的第一地理围栏数据中蜂窝小区信息相同，且/或，电子设备100检测到的Wi-Fi数据与第一地理围栏数据中Wi-Fi数据匹配，且/或，电子设备100检测到的GNSS位置与第一地理围栏数据中GNSS位置匹配时，电子设备100可以确定电子设备100进入到第一活动区域内车库的地理围栏。
在一种示例中，电子设备100上的GNSS模块处于关闭状态，在电子设备100通过蜂窝小区信息和/或Wi-Fi数据，确定电子设备100进入到车库的地理围栏且电子设备100处于车载状态后，电子设备100才开启GNSS模块，获取GNSS数据。然后，电子设备100基于GNSS模块获取到的GNSS数据和IMU数据，持续进行导航定位，获取电子设备100的实时位置。GNSS数据包括GNSS观测量，或者，GNSS数据包括GNSS观测量和GNSS位置。
其中，当电子设备100基于IMU数据判断电子设备是否处于车载状态时，IMU可以在判断电子设备是否处于车载状态之前就开启。当电子设备100基于其他方式(例如，电子设备100是否与车辆建立了蓝牙连接)判断电子设备100是否处于车载状态时，IMU可以在判断电子设备是否处于车载状态之前就开启，也可以在确定电子设备100进入到车库的地理围栏且电子设备100处于车载状态时，才开启。这样，节约电子设备100的功耗。
在一种示例中，电子设备100可以先识别电子设备100的AR状态，并判断电子设备100的AR状态是否为车载状态。当确定出电子设备100的AR状态为车载状态后，再判断电子设备100是否进入到第一活动区域内车库的地理围栏。这样，可以在识别到电子设备100处于车载状态时，才检测电子设备100是否进入到车库的地理围栏，节约了电子设备100的功耗。
在另一种示例中，电子设备100可以先判断电子设备100是否进入到第一活动区域内车库的地理围栏。当电子设备100确定进入到第一活动区域内车库的地理围栏后，电子设备100再识别电子设备100的AR状态，并判断电子设备100的AR状态是否为车载状态。这样，可以在电子设备100进入到了地库的地理围栏后，才识别并判断电子设备100的AR状态，节约了电子设备100的功耗。
S807、当电子设备100的AR状态为车载状态且电子设备100进入到第一活动区域内的地理围栏时，电子设备100可以通过导航定位模块持续定位，获取电子设备100的实时位置。
其中，导航定位模块中的VDR模块可以基于IMU数据确定出电子设备100的位移信息，GNSS定位模块可以通过GNSS模块获取到的GNSS位置和观测量信息，进行高精度定位解算，得到高精度位置信息。导航定位模块可以融合移动位移和高精度位置信息，持续获取电子设备100的实时位置。当导航定位模块无法获取到GNSS模块发送的GNSS位置和观测量信息时，导航定位模块可以获取到GNSS定位模块上一次解算出的高精度位置信息。VDR定位模块可以基于IMU数据解算出目标时间段内电子设备100的位移信息，其中，目标时间段为GNSS定位模块上一次解算出高精度位置信息的时刻到当前时刻。导航定位模块可以基于上一次解算出的高精度位置信息和目标时间段内电子设备100的位移信息，确定出电子设备100在当前时刻的位置。
例如，当电子设备在第一时刻到通过GNSS模块获取到GNSS数据时，电子设备基于该GNSS数据，解算出电子设备在第一时刻的位置；当电子设备在第二时刻未通过GNSS模块获取到GNSS数据时，电子设备基于IMU数据，确定电子设备在第一时刻到第二时刻之间的位移信息；该电子设备基于该电子设备在该第一时刻的位置和第一时刻到第二时刻之间的位移信息，确定出电子设备在第二时刻的位置。
S808、当电子设备100检测到车辆处于停车状态时，将电子设备100当前的位置记录为停车位置。
在一种示例中，电子设备100可以从IMU数据中确定出电子设备100的移动速度。当移动速度满足第二预设条件时，电子设备100可以确定电子设备100处于停车状态。例如，第二预设条件可以包括电子设备100的移动速度为0。
在一种示例中，当车辆停车熄火时，车辆可以通过蓝牙连接向电子设备100发送车辆状态信息2，该车辆状态信息2用于指示车辆已停车。当电子设备100接收到车辆状态信息2时，电子设备100可以确定车辆处于停车状态。
在一种示例中，当电子设备100检测到电子设备100与车辆之间的蓝牙连接断开时，电子设备100可以检测到车辆处于停车状态。
在电子设备100获取到停车位置后，电子设备100可以输出提示信息，该提示信息用于给用户提示车辆的停车位置。
在一种示例中，电子设备100可以在获取到停车位置后，在地图中标记出电子设备100的停车位置。
示例性的，如图9A所示，电子设备100可以显示出桌面上所有页面中最左边的一个页面910。该页面910可以包括多个应用图标(例如，天气应用图标、股票应用图标、计算器应用图标、设置应用图标、邮件应用图标、图库应用图标、音乐应用图标、视频应用图标、浏览器应用图标)。多个应用图标下方还包括页面指示符911，该页面指示符911表明当前显示的页面910其他页面的位置关系，页面指示符911的下方有多个托盘图标(例如，拨号应用图标、信息应用图标、联系人应用图标、相机应用图标)，托盘图标在页面切换时保持显示。页面指示符也可以不是页面的一部分，单独存在。上述的托盘图标也是可选的，本申请实施例对此不做限制。

如图9B所示，该负一屏界面920可以包括停车卡片921和一个或多个快捷功能控件(例如，搜索控件、扫一扫功能控件、付款码功能控件、手机充值功能控件、更多功能控件，等等)。其中，该停车卡片921中可以显示有地图922、停车地点名称(例如商场A的地下停车场)、停车时长(例如，约1分钟)、停车位置与当前位置的距离(例如，50米内)，等等。地图922中可以显示有车辆的停车位置对应的标记923、电子设备100当前的位置对应的标记924。可选的，该停车卡片921还可以显示有导航控件925，该导航控件925可以用于触发电子设备100显示出当前位置到停车位置的路线指引。
上述示例仅仅用于解释本申请，电子设备100显示停车位置的方式不限于在负一屏界面还可以在其他界面，例如车应用的界面中，在此不再赘述。
在一些实施例中，导航定位模块中还可以包括有航位推算(DR)定位模块。其中，DR定位模块可以适用于用户在骑车过程中的惯性导航。因此，当检测到电子设备100的AR状态为骑行状态时且电子设备100进入到某个地理围栏中时，电子设备100可以调起导航定位模块中的DR定位模块和GNSS定位模块，持续定位。电子设备100在检测到停车时，可以记录并输出停车位置。
本申请实施例中提供了一种定位方法，可以实现给多个室内区域(例如，车库、隧道、山洞，等等)配置地理围栏。在电子设备上的导航定位模块没有被开启的情况下，若电子设备检测到进入指定室内区域的地理围栏且电子设备处于车载状态后，电子设备可以启动导航定位模块，发起持续定位，当电子设备检测到停车时，获取到停车位置。其中，导航定位模块包括GNSS定位模块和VDR定位模块/DR定位模块。这样，电子设备可以在识别到将要进入到室内区域时，自动开启导航定位模块，以获取电子设备进入到室内区域内的实时位置。
